Every Conservatory Style, Priced
Almost every style comparison published in the UK quotes each style at whatever size its source happened to price, which makes the cheapest style look cheaper than it is and the dearest look dearer. This page does the opposite: every style is quoted at a matched footprint, four times over, and where a style has no matched comparison it is shown on its own and labelled as such. The rate behind all of it is reconciled in the per square metre table.

Lean to conservatory prices, and what every other style costs
A uPVC lean-to at 4m by 3m costs £9,000 to £14,000 installed and including VAT, typically £11,800, which we grade Reasonably evidenced from two publishers whose bands nest. At the same 12 m² footprint a Victorian is £11,000 to £18,000, an Edwardian £10,000 to £19,000 and a gable end £10,800 to £12,000. Checked 20 August 2026.
Lean-to is the cheapest style in every source we hold and the reason is shape rather than specification. A rectangular plan and a single pitched roof need less frame, less glazing and fewer labour hours than a faceted plan enclosing the same floor area. That is also why the saving is real: you are not buying a thinner glazing unit or a lighter frame, you are buying a simpler geometry. Across the whole register the cheapest published floor by style runs lean-to £8,000, Victorian £9,000, Edwardian £10,000 and P-shape £13,250, each at the smallest size its own source prices, all installed including VAT and checked 20 August 2026.
Those four floors are the numbers that circulate, and on their own they are misleading, because three different footprints are hiding inside them. The table below fixes that. You can also price your conservatory against your own style and size rather than reading across from ours.
Every style at a matched size
Four matched footprints, in ascending order. Read across a block and the comparison is honest; read across blocks and it is not. All rows are uPVC, whole build, installed, including VAT, and every figure was checked on 20 August 2026.

Sources by block: Publisher B, April 2026, and Publisher A's lean-to guide, July 2026, at 9 m²; Publisher A's style table, June 2026, at 12.25 m², which is the only source publishing that size by style; Publisher A, Publisher D of 24 June 2026 and Publisher C of 28 January 2025 at 12 m² and 16 m². Rows graded Thin have one publisher behind them. Publishers are lettered rather than named on this page, and the same letter is the same publisher throughout. Checked 20 August 2026, next check due 20 November 2026.
Three readings the matched blocks make possible and the usual mixed-size table does not. First, the gable end has the tightest cross-source agreement in the whole new-build dataset: two independent publishers seventeen months apart land within 1.07× at 12 m² and 1.11× at 16 m². Second, tiling the roof rather than glazing it is a visible step in the one source that prices the same style both ways: £3,300 on a lean-to at 12 m² against its own glazed figure, and £4,550 on a gable end at the same size against its polycarbonate one. Third, the style premium collapses as the footprint shrinks: at 9 m² only £2,000 separates the cheapest floor from the dearest, which is the whole argument on the cost of a small conservatory.
The row that inverts, and the row we exclude
The 16 m² block above comes from a single publisher, Publisher C, and it is at once the richest style-by-size-by-roof dataset in UK public data and the one row set we treat with the most suspicion. At 4m by 4m it prices a lean-to at £14,200 against an Edwardian at £13,300, which puts the simplest shape above the more complicated one and inverts every other source we hold. Publisher A in June 2026 has the lean-to at 0.91 of the Edwardian at a comparable size, which is the direction every other publisher agrees on.
We publish the figures as they were published and flag the inversion on the row. What we do not do is use that block to derive a style multiplier, because a factor built on an inverted pair would propagate the error into every size we do not have data for. If you want the ordering rather than the arithmetic: at every size with more than one publisher behind it, lean-to is the cheapest and the faceted plans cost more.
One figure from the same matrix is excluded outright. Its T-shape at 5m by 3.5m in polycarbonate is published at £12,400, which is less than the same source charges for the same style at 5m by 3m, a smaller room. A price that falls as the room grows is a transcription error rather than a market signal, so it does not appear in any band on this page and the T-shape rows below are built without it.
P-shape is the best-evidenced style we hold
A P-shape at 15 to 20 m² costs £13,250 to £19,700 installed including VAT, typically £16,750. That is graded Well evidenced, and it is the only style row in the new-build data that clears the bar: three independent publishers, Publisher D on 24 June 2026, Publisher A in May 2024 and Publisher C on 28 January 2025, contribute six overlapping data points, with the floors inside 1.06× of each other and the ceilings inside 1.19×. The typical is Publisher A's own stated figure and it sits inside every other source's band, so nothing had to be invented to produce it. Checked 20 August 2026.
It is also the style whose price is easiest to explain. A P-shape is two rooms joined, usually a lean-to run and a projecting square or faceted section, and it prices like two rooms. If the shape appeals but the number does not, the honest alternative is a bigger single-run plan rather than a smaller P-shape, because the junction between the two sections is where the cost sits.
Styles the register prices at one size only
These have no matched comparison anywhere in UK published pricing, so they are shown alone rather than dropped into a table beside styles measured differently. All installed, including VAT.
| Style and size | Low | Typical | High | Evidence | Source |
|---|---|---|---|---|---|
| P-shape, 15 to 20 m² | £13,250 | £16,750 | £19,700 | Well | Publishers D, A and C |
| T-shape, 5m × 3m (15 m²) | £12,750 | £13,750 | £17,600 | Reasonably | Publisher D Jun 2026, Publisher C Jan 2025 |

| Lantern, 5m × 4m or 6m × 4m | £20,000 | not published | £25,500 | Thin | Publisher D Jun 2026 |
Every row here except the P-shape has one or two publishers behind it and is graded accordingly. A lantern is a roof form rather than a plan shape, so the row prices a whole conservatory built with one and is not comparable to the plan-shape rows above it. Checked 20 August 2026.
Three styles nobody in the UK prices
Publishing the gap is more useful than filling it, so here is what we looked for and did not find.
| Style | What we found | What would close it |
|---|---|---|
| Bay Victorian | No UK source publishes a price | Three installer quotes for the same footprint in Victorian and Bay Victorian, or a manufacturer price list |
| Bay Edwardian | No UK source publishes a price | As above, matched against a plain Edwardian |
| Bespoke | No mainstream UK source publishes a bespoke line | A named architect or bespoke maker publishing a rate per square metre with the specification attached |
Both bay variants are styles installers actively sell, which is what makes their absence worth stating. The nearest anchor we hold for a bespoke build is a published £15,000 to £25,000 for rebuilding a conservatory as a full extension, Publisher A, May 2024, single source, graded Thin, and that is a different job rather than a bespoke conservatory. Two named absences worth recording: two well-known oak and orangery specialists publish pages whose URLs promise costs and which contain no price figures at all. Checked 20 August 2026.
What sits under every style figure
Every band on this page is uPVC, glazed roof unless the row says otherwise, and includes the base, the dwarf wall where the style carries one, fitting and VAT. Three decisions move a style figure more than the style does.
The frame material
Published as a premium over uPVC rather than as a total, which means it applies on top of every row above. Aluminium is the better-evidenced premium of the two and, awkwardly for the way it is usually sold, it is the thermally worse material. The premiums, the totals behind them and the reason the two move in opposite directions are on what the frame material costs.
The base and the dwarf wall
Lean-to, Victorian and Edwardian plans usually sit on a dwarf wall and a fully glazed lean-to usually does not, so two rows in the same block can be carrying different groundwork. It is the biggest single source of variance between two quotes for the same room and no UK cost site has a dedicated guide to it, so we built one: conservatory base and groundwork cost.
Whether fitting is in the price
A style price that looks 20 per cent cheaper than everything around it is usually not a cheaper conservatory. One manufacturer's £9,725 lean-to excludes the base, the floor, the walls and the fitting. The line-by-line difference is supply only against supply and fit.
With those three settled you can see what yours would cost at your own style and size, with the evidence grade shown beside the band rather than behind it.
Planning permission follows the footprint, not the style
No style on this page is treated differently by the planning system. What matters is how far the structure projects, how much of the garden it covers, how tall it is and whether the house sits on designated land. A P-shape and a lean-to enclosing the same area are assessed the same way, which is why the size limits, and the conditions that remove the rights altogether, are set out at permitted development for a conservatory.
The one place the style does bite is the roof. A conservatory under 30 m² at ground level is normally exempt from the building regulations while it stays thermally separated from the house with a translucent roof. The tiled roof rows in the matrix above describe structures that do not meet that description, and that is a regulation difference rather than a price difference.
Where a style stops being a conservatory
Push a gable end or a P-shape far enough up the specification, with a heavier frame, more brickwork, a lantern instead of a full glazed roof and a plastered ceiling, and it becomes an orangery. That is a different product with a different price bracket entirely, and pretending otherwise is how a £16,750 P-shape turns into a £33,000 quote between the showroom and the survey. The comparison, with both sets of published figures, is on conservatory vs orangery.
Price your own style and size
Six questions, about sixty seconds, and an estimate built from the rows above with the grade and the source shown beside each one.
Where we hold no defensible figure for a style and size combination, the estimate says so rather than interpolating between two rows, which is why three styles on this page show a gap. If you already own a conservatory and it is the roof you are replacing rather than the whole structure, the numbers are lower than these but not by much: £8,075 against £10,000 at 3m × 3m, and £8,000 to £14,400 against £14,900 at 4m × 4m. You can compare local conservatory roof installers once you know the size. For the whole-structure figures behind everything here, the same rows sit under the Conservatory Cost Calculator.
